Which sentence has the correct punctuation?

Correct option is B

The correct sentence is (b) Sarah's studying German, Physics and Chemistry this year.

Explanation:

• The sentence requires correct punctuation to separate the items in the list (German, Physics, and Chemistry). A comma is appropriately used before listing multiple subjects to ensure clarity.
• The contraction "Sarah's" is correct, indicating Sarah is.

Grammatical Rule Used:

1. Use a comma to separate items in a list of three or more.
2. Apostrophes in contractions like "Sarah's" replace the omitted letter (in this case, "i" from "is").

Rule in Hindi: वाक्य में वस्तुओं या विषयों की सूची देते समय, आइटम्स को अलग करने के लिए कॉमा का उपयोग किया जाता है।

Why Other Options Are Incorrect:

• (a) Sarah studying German; Physics and Chemistry this year: The semicolon (;) is incorrectly used because it is meant to separate independent clauses or items with internal punctuation.
• (c) Sarah's studying German: Physics and Chemistry this year: The colon (:) is misused here; a colon introduces an explanation or elaboration, not a simple list.
• (d) Sarah's studying German Physics Chemistry this year: Missing commas make the sentence unclear and grammatically incorrect.

Key Takeaway: Use commas to separate items in a simple list, and use apostrophes correctly for contractions.
Example: She's studying Math, Biology, and Literature this semester.
